Our data set is a sample set of accidents and related accident data compiled by the National Highway Traffic Safety Administration (NHTSA) 2018. Our specific data set is comprised of data from the Crash Report Sampling System(CRSS). This data is a sample of police reported accident data relating to many different aspects of an accident, including pedestrian, motor vehicle, property, etc. Every year, there are more than 6 million reported accidents, and this data set compiles data on accidents that are “of greatest concern to the highway safety community and the general public”.
Our objective is to gain a deeper insight into different aspects of accident trends. We have focused on a few different areas of accidents, including alcohol use as it relates to other data, area of the US, and others.
